Me personally I would go out of my friggin mind on that stack. Ephedra really works me into a hyperactive nut job, and in the uber focus feeling i get from venom + caffiene. Spells trouble fo me. IMHO if you did do this I would take the venom in the morning for the lasting appetite control, then use the ephedra mid afternoon, or PWO for an energy boost. Good luck. You should log it if you do it. I would be interested to know how you feel on the stack.
